I like that this formulation does not mega dose B6, though the mega doses of other B vitamins mean this formula is not right for me. If this review was helpful to you, please click YES below - thank you. For reviews of all the products I have purchased from iHerb, please click my username above.

I've used it for a week and I can feel the energy as odd as that sounds but usually I would drink two 8 oz cups of coffee by 2pm and I haven't had a caffeine urge. I have mthfr so the combinations of vitamins works for me.
I had given it 5 stars and changed it to 1.
Update: After a year of having a bottle half full... I can say I didnt get through the bottle. I felt good mid day but by the evening hours I had such a bad headache concentrated right above my eyes. I tried once again after I stopped taking them and the same concentrated eye headache came back along the burpy feeling. I switched to another multivitamin that didnt have me squinting my eyes and they have the same amount of methylfolate and same vitamins but different doses of them.
